hit delete when you restart you computer to go into the bios, then look in advanced bios features it may be under "Integrated Peripherals", look in there for (Most likely) "AC97 Audio Device", set it to disabled. Remember when you exit the BIOS, use the "Exit and save settings" option.

It could also be listed under Chipset Features, depends on which BIOS producer is involved; use the + or - key to enable or disable onboard sound and, as Aol Hater points out, don't forget to Exit and Save the settings.
